Same-Sex Couples & Surrogacy

Where the parentage gap is not an abstraction but a daily condition.

For a two-father family formed through surrogacy, the Irish parentage gap is not a technicality to be managed — it is the structure of the household in the eyes of the law. One parent is a parent. The other is not. Same house, same child, same school run.

Position stated as at 31 July 2026. The principal surrogacy provisions of the Health (Assisted Human Reproduction) Act 2024 were not commenced at that date. Commencement changes this position materially and can happen at short notice — confirm the current status before acting on anything here.

Two Fathers, Two Mothers, Two Different Problems

Two-father families reach parenthood through surrogacy, which is the arrangement Irish law has least provided for. The biological father can generally establish parentage and seek guardianship. The other father has no route to parentage at all under the law as it stands, and must look to guardianship — which carries qualifying conditions, confers less, and expires at eighteen. Two-mother families are frequently better placed and by no means always, and the assumption that they are covered causes genuine harm. Where a child was conceived through donor-assisted reproduction meeting the requirements of the Children and Family Relationships Act 2015, there is a route by which the birth mother’s partner can be a legal parent. Where treatment happened abroad, or before the relevant provisions, or informally without clinical involvement, that route may simply not be available — and those are common situations, not edge cases. Provision has also been made addressing certain female same-sex couples who undertook home insemination before a specified date, which tells you how fact-specific this territory is. Establish the position; do not assume it. And note the assumption that catches most people: marriage does not confer parentage. The spouse of a biological father does not become a legal parent by reason of the marriage, and the surrogate remains the legal mother. Marriage matters for which guardianship route is open and for planning between the adults. It does not close the gap.

What to Secure Now, and What the Act Would Change

Guardianship for the second parent as soon as the route is available, because it materially improves daily life and is the practical priority. Whatever parentage the biological or birth parent can establish, formalised rather than assumed. Documentation and travel sorted properly. Wills on both sides, drafted so the parentage gap is addressed explicitly — for these families the intestacy and will-construction risks are acute, and a will leaving everything to “my children” without defining them is a genuinely dangerous document. Medical and school consents. And the evidence a future application would need, preserved — including, for surrogacy families, the ability to contact the surrogate, which is the thing most easily lost over years of waiting. As for the 2024 Act: the parental order mechanism transfers parentage regardless of the couple’s sex, and Part 12 would provide a retrospective route — but the conditions apply equally, including gestational surrogacy, a genetic link to at least one intending parent, non-commercial arrangements, and residence requirements for past arrangements. Some families will qualify comfortably; some will not. Advice on your specifics is worth considerably more than general reassurance, and none of the “secure now” list should wait for it.

One of You a Parent in Law, and One Not?

It is the most common position for Irish same-sex families formed this way, and a good deal more can be done about it than most people have been told.

Because surrogacy is the route, and surrogacy is the arrangement Irish law has least provided for. In a two-father family formed through surrogacy the biological father can generally establish his parentage and seek guardianship; the other father has no route to parentage at all under the law as it currently stands, and must look to guardianship, which carries qualifying conditions and expires at eighteen. The result is a household in which one parent is a parent in law and the other is not, with everything that follows in medical consent, school, travel and - most consequentially - inheritance. It is not a marginal technicality for these families; it is a daily condition.

General information, not legal advice. This website contains general information about Irish law relating to surrogacy and assisted human reproduction. It is not legal advice and does not create a solicitor—client relationship. Every family’s position turns on its own facts, and advice on yours requires a consultation.

The law is changing and this page has a date. The position described across this site is stated as at 31 July 2026. The principal surrogacy provisions of the Health (Assisted Human Reproduction) Act 2024 were not commenced at that date. Commencement orders can be made at short notice and will alter this position materially. Confirm the current position before acting.

This is a legal practice, not an agency. Mary Molloy Solicitors provides legal advice and representation. It does not operate as a surrogacy agency, does not match, introduce or recruit surrogates or intending parents, does not advertise for or on behalf of any surrogate, does not recommend or receive any payment from any clinic, agency or intermediary, and takes no part in arranging or facilitating any payment beyond the provision of legal services. Nothing on this site is an offer or invitation to enter any commercial surrogacy arrangement.

Foreign law and medical matters. Where an arrangement involves another jurisdiction, the law of that jurisdiction applies to what happens there and independent legal advice must be taken locally — nothing here states or implies that any arrangement is lawful or unlawful in any other country. Nothing on this site is medical advice, and questions about treatment, suitability or risk are for your treating clinicians.

Fees. Fees are agreed in writing with the client at the outset. In contentious business, a solicitor may not calculate fees or other charges as a percentage or proportion of any award or settlement.

Tax. Nothing on this website is tax advice. Where parentage affects succession, gift or inheritance treatment, those questions belong with your accountant or tax adviser and with Revenue’s own guidance, and should be addressed before any step is taken.
